Negative Pressure Wound Therapy (NPWT), commonly known as VAC (Vacuum-Assisted Closure) therapy, is an advanced wound management system used to promote healing in complex, chronic, traumatic, surgical, and non-healing wounds. The system uses controlled negative pressure to remove excess fluid, reduce infection risk, improve blood circulation, and stimulate healthy tissue growth.
Overview
VAC therapy involves placing a specialized foam or dressing over the wound, which is connected to a sealed vacuum system that applies controlled suction. This negative pressure helps remove wound exudate, decrease swelling, improve tissue oxygenation, and support faster wound healing. NPWT systems are widely used in burn care, diabetic ulcers, pressure sores, traumatic wounds, post-surgical wounds, graft stabilization, and reconstructive surgery.

Understanding The Procedure
Symptoms Negative Pressure Wound Therapy (VAC)
Risks
- ⦾ Pain or discomfort during dressing changes
- ⦾ Bleeding or tissue irritation in sensitive wounds
- ⦾ Infection risk if dressing protocols are not maintained properly
- ⦾ Need for regular monitoring of wound healing progress
- ⦾ Skin irritation or leakage around dressing seal areas
Post-Operative Care
- ⦾ Regular monitoring of wound condition and VAC system function
- ⦾ Scheduled dressing changes under sterile conditions
- ⦾ Infection prevention and wound hygiene management
- ⦾ Nutritional support and hydration to improve healing
- ⦾ Follow-up wound assessment and rehabilitation support when required
Long Term Outlook
The long-term outlook with Negative Pressure Wound Therapy is highly positive because modern VAC systems significantly improve wound healing, reduce infection risk, and support tissue recovery in complex wounds. Early intervention, proper wound care management, nutritional support, and continuous medical follow-up are important for maintaining successful long-term healing and functional outcomes.
